NOTES:
X = No Effect
1. PV limit substatus reflects only READBACK limit substatus. SP limit substatus reflects only out block rate limits.
2. Firmware Revision 1.1 and earlier will set AO/DO PV Status to Bad if Feedback Sensor has failed, ie; Travel Sensor Fail. However, if the Travel Sensor fails, and the instrument
falls back to pressure, PV Status will remain good.
